Copper-alloy, 20.11 grams, 63.71 mm. 11th-12th century AD. A pair of cast swivel-mount rings, each loop formed as a pair of opposed zoomorphic heads clutching the swivel-half in its jaws. The attachment tags are still in place, which were riveted in three places to the leather straps. The loops are segmented with transverse banding, which extends on to the swivel halves. The swivel is created from two hemispherical sections, one with a pin and the other pierced. The pin is inserted through the piercing and flattened over to trap it. The piece is complete and articulated. Reference: Mills, N. Medieval Artefacts, Witham, 2003, p.19. Extremely fine condition.
